The Largest Bridge of Phnom Penh-Sihanoukville Port Expressway Project CompletedDate: 12/06/2021
On November 30, the box girder of the largest K178+267.5 bridge of Cambodia's Phnom Penh-Sihanoukville Port Expressway Project was completed.
The K178+267.5 bridge spans Kbal Chhay Waterfall River, with a total length of 225 meters and a design of 3 connections and 9 spans. The superstructure adopts prestressed concrete (post-tensioned) simply supported small box girder, the substructure adopts ribbed slab abutment, the pier adopts column pier, the abutment adopts pile foundation, and the maximum pile foundation diameter is 2 meters. The K178+267.5 bridge is the one with the longest span and the most difficulty in construction. In view of the limitations of the bridge, such as large terrain fluctuation, poor engineering geological conditions, long rainy season and short effective operation time, the project “tailored” the working plan by strengthening the construction organization, adopting a variety of construction techniques and paying attention to process quality and safety supervision to ensure the construction quality and progress.
As Cambodia's first expressway, the Penh-Sihanoukville Port Expressway will connect the capital Phnom Penh City and Sihanoukville Port, the country's largest seaport, with a total length of about 187.05 kilometers. After completion, it will significantly shorten the journey between the two cities, greatly promote the economic development of Cambodia and improve the local livelihood.
